The number of PDO that the HTB unit can use is 16 in total. As all the objects cannot be mapped, please map only required objects to PDO.
For HTB and EX module standard outputs, do not perform write operations from multiple objects.
When the analog module is connected to the HTB and after CANopen communication between the GP and LT unit is established, error code 155 (Slave Configuration Error) may appear upon resetting either the GP or LT unit.
If the HTB is used, for the recovery feature for the parameter, the application data is not recovered even if [Application Only] is selected.
With GP-Pro EX V2.5 or later, EDS files for the HTB are built-in. They do not need to be downloaded from “Otasuke Pro!” and imported.
The maximum number of Analog Input channels is 24 channels. Therefore, when connecting 8 channel modules, up to 3 modules can be connected.
When input from modules with the input points greater than 8 bits, follow one of the methods below.
Use 16-bit input (6000) object instead of using multiple 8-bit input (6000) objects
Map multiple 8-bit input (6000) objects to the same PDO
When connecting Analog Output EXM modules to HTB, make sure to stay within the limit. When exceeding the limit, out-of-range data may be generated in the margin.
When configuring Analog Output Upper or Lower limit (such as object 2202h, 2203h), configure a range that includes 0. An error may occur at the start of communication if the initial Analog Output Upper and Lower Limits do not include 0.
When HTB equipment is Standard Output, it will not function even if [Restore] is set to [None]. (Reset when communication cable goes from disconnected -> restored (connected).)
When using analog module connected to HTB, it will not function even if [Restore] is set to [None]. (All parameters are restored when communication cable goes from disconnected -> restored (connected).)
When using inputs less than the Lower Limit for the Input Range on the EXM-AMI4LT, an input range error is detected unless the voltage setting is about -1 V and current setting is about -4 mA. Using inputs less than the lower limit could influence other CH, and lower their input values..
